DETAILED DESCRIPTION

Described herein, inter alia, are adipolytic formulations, non-invasive methods and systems, and kits for body contouring, including reducing, emulsifying, and/or eliminating subcutaneous adipose tissue, including fat deposits. These formulations have been shown to be beneficial, for example, for emulsifying and destroying cell membranes of adipose tissue. Also, described herein is the identification of formulations that contain appropriate excipients that can provide important temperature stability and anti-foaming properties without the drawbacks associated with currently used excipients (e.g., ethanol).

In embodiments, excipients are provided that avoid reduction in the detergent/emulsifying activity of the polidocanol and impediment of the fat destruction effect. In embodiments, certain surfactant excipients do not improve the temperature stability and may worsen problems with foaming. In embodiments, the excipients identified herein have suitable solubility in buffered, isotonic saline solution. Excipients provided herein may have a high safety profile where used for localized destruction of fat, which may be considered an aesthetic indication for which an increased showing of safety may be desired.

Polidocanol and polidocanol-like compounds are disclosed herein. Polidocanol is usually soluble in water and typically does not require an emulsion, such as a micro-emulsion, formulation for administration. Polidocanol typically does not denature proteins like ionic detergents. Polidocanol may solubilize cell membranes thereby disrupting the cell and tissue leading to cellular and tissue death. In embodiments, this solubilization leads to a more selective and targeted effect on fat tissue and minimizes collateral effects on non-targeted tissues and structures. In embodiments, polidocanol has an average HLB of approximately 13. In embodiments, polidocanol has an average HLB of approximately 12. In embodiments, polidocanol has an average HLB of approximately 12, a critical micelle concentration of approximately 0.07-0.10 millimolar, and an aggregate number of 75-100 and is considered a mild detergent or surfactant. In embodiments, a cosolvent may be used to improve long term stability of polidocanol solution formulation in the range of about 2-40% (W/V).

As used herein, the term “polidocanol-like compound” refers to a compound of Formula I or Formula II described herein, including embodiments thereof.

An “effective amount” is an amount sufficient to accomplish a stated purpose (e.g. achieve the effect for which it is administered, treat a disease, reduce adipose tissue or cells, lyse cells, reduce one or more symptoms of a disease or condition). An example of an “effective amount” is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease or condition, which could also be referred to as a “therapeutically effective amount.” A “therapeutically effective amount,” as used herein, refers to a sufficient amount of an agent (e.g., polidocanol) or other compound being administered which will relieve to some extent one or more of the symptoms of the disease or condition being treated. The result can be reduction and/or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. For example, an “effective amount” for therapeutic uses may be the amount of the composition including a compound as disclosed herein required to provide a clinically significant decrease in disease symptoms without undue adverse side effects. An appropriate “effective amount” in any individual case can be determined using techniques, such as a dose escalation study. The term “therapeutically effective amount” includes, for example, a prophylactically effective amount. An “effective amount” of a compound disclosed herein, such as polidocanol used alone or in combination with other compounds, is an amount effective to achieve a desired pharmacologic effect or therapeutic improvement without undue adverse side effects. It is to be understood that “an effective amount” or “a therapeutically effective amount” can vary from subject to subject, due to variation in metabolism of a compound of Formula I or Formula II as described herein (such as polidocanol), age, weight, general condition of the subject, the condition being treated, the severity of the condition being treated, and the judgment of the prescribing physician. A “cosmetically effective amount” as used herein refers to the amount of a compound sufficient to improve the outward physical appearance of a subject. The outward physical appearance of a subject includes, for example, the reduction of fat deposition in certain regions of the body including, for example, the midsection of the body. In embodiments, a cosmetically effective amount refers to a sufficient amount of an agent (e.g., polidocanol) which will improve the cosmetic appearance at the localized site of treatment. A cosmetically effective amount of polidocanol may be an amount effective to achieve a cosmetically desirable improvement. It is to be understood that a cosmetically effective amount can vary from subject to subject, due to numerous factors including for example age, weight, general condition of the subject, the condition being treated, the severity of the condition being treated, and the judgment of the prescribing physician. For example, a cosmetically effective amount of an agent (e.g., polidocanol) may be an amount capable of improving the cosmetic appearance at the localized site of treatment by reducing the amount of adipose tissue or cells at the localized size or an area adjacent to the localized site of treatment.

In certain embodiments, the phrase “pharmaceutically acceptable salt(s) and other suitable forms”, and similar language as used herein, means those salts, solvates, hydrates, and other suitable forms of compounds described herein that are safe and effective for administration in mammals.

SCI. 1-19 (1977), incorporated in entirety by reference herein.

“Pharmaceutically acceptable excipient” and “pharmaceutically acceptable carrier” refer to a substance that aids the administration of an active agent to a subject and can be included in the compositions described herein without causing a significant adverse toxicological effect on the patient. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer's, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, mannitol, gum acacia, calcium phosphate, alginates, tragacanth, calcium silicate, microcrystalline cellulose, cellulose, syrup, and methyl cellulose, colors, and the like. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl and propylhydroxy benzoates; sweetening agents; and flavoring agents. The compositions described herein can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. One of skill in the art will recognize that other pharmaceutical excipients are useful in the present invention.

Any suitable pharmaceutically acceptable excipient appropriate for a particular route of administration can be used. Examples of pharmaceutically acceptable carriers include, but are not limited to, buffers, saline, or other aqueous media. The compounds of the invention are preferably soluble in the carrier which is employed for their administration (e.g., subcutaneous). Alternatively, a suspension of the active compound or compounds (e.g., a suspension of microparticles) in a suitable carrier is employed. Some embodiments include any suitable lipophilic carrier, for example, modified oils (e.g., CREMOPHOR® BASF, Germany), soybean oil, polyethylene glycol, derivatized polyethers, combinations thereof, and the like. Some embodiments include a microparticulate and/or a nanoparticulate carrier. Some embodiments include one or more sustained or controlled release carriers or agents, for example, polymer microspheres. Some embodiments include excipients suitable for stable suspensions for micronized particles of polidocanol. In further or additional embodiments, the formulations include an immediate release excipient. In embodiments, the pharmaceutically excipient is not a C₃-C₆ alcohol (e.g. propylene glycol).

The term “fat pad” refers herein to any cushions made of a pocket of fascia and filled with fat deposits (e.g. fatty acids) that are present in humans or mammalians.

As used herein, “administering” means administering by any route, including local, parenteral, by infusion, injection, implantation, or subcutaneous administration. For example, the formulations described herein can be administered by subcutaneous injection or delivery. For example, the formulations described herein can be administered by intravenous injection or delivery. As used herein, a formulation formulated for subcutaneous injection can include sterile isotonic aqueous buffer. Where necessary, the compositions can also include a solubilizing agent.

Embodiments of the composition are formulated for administration by any suitable method, for example, as described in Remington: The Science And Practice Of Pharmacy (21st ed., Lippincott Williams & Wilkins). Exemplary routes of administration include, but are not limited to parenteral, oral, subcutaneous, topical, intramuscular, transdermal, transmucosal, sublingual, intranasal, transvascular, subcutaneous, orbital, or respiratory. In some embodiments, the composition is formulated for injection of an area at which treatment is desired, for example, in a regional fat deposit, such as for example excessive sub-mental adiposity. In some embodiments, provided are methods for subcutaneous delivery as well as compositions and formulations that are formulated to be suitable for subcutaneous delivery.

Injectable formulations are administered using any method known in the art, for example, using a single needle, multiple needles, and/or using a needleless injection device. In some embodiments, a tissue loading dose of the active ingredients formulated in a suitable carrier delivered by injection. In some embodiments, delivery includes single needle injection. In some embodiments, delivery includes injection using a multi-needle array, which, in some embodiments, provides a wide dispersion of the formulation in the target tissue. In some embodiments, formulations are injected in a manner that allows dispersal into the appropriate layer of subcutaneous fat in areas where regional fat exists. In some embodiments, a micropump is used to deliver the injectable formulations.

The formulations described herein may also be administered via a device. A number of devices have been proposed to facilitate self-administration of pharmaceutical formulations. The device typically includes a reservoir containing, for example, pre-loaded with, the pharmaceutical formulation to be administered. For example, a micropump can provide precise subcutaneous administration of small quantities of a liquid pharmaceutical formulation. Such micropumps can be compact and portable. Another type of device useful for subcutaneous delivery or administration of pharmaceutical formulations is often referred to as a patch device or a pump-patch device. Patch devices usually are attached directly to the skin of a patient.

Accordingly, in various embodiments, a device such as a micropump or patch device can include a reservoir containing a pharmaceutical formulation, a subcutaneous injection needle configured for removable insertion into skin of a patient, a micropump having an inlet in fluid communication with the reservoir and an outlet in fluid communication with the subcutaneous injection needle, a control system configured for controlling the micropump to deliver the pharmaceutical formulation from the reservoir to the subcutaneous injection needle, whereby the pharmaceutical formulation is administered subcutaneously to a patient, and a housing for supporting the reservoir, subcutaneous injection needle, micropump and control system, the housing being portable and adapted for contact with the skin of the patient. The pharmaceutical formulation contained within the reservoir can be any of the pharmaceutical formulations of the present teachings, for example, a pharmaceutical formulation including an effective amount, including for example a therapeutically or cosmetically effective amount, of polidocanol and from about 0.5% W/V to about 10% W/V of an alcohol having 3 to 6 carbon atoms (i.e. a C₃-C₆ alcohol).

In certain embodiments, the device can be of a unitary construction. Such devices can be for a single or one-time use. In particular embodiments, the device can be of a multi-piece construction, in such devices, a disposable or a re-sizeable portion or component can be present. For example, a housing defining or including the reservoir can be a disposable or a reusable component of the device, in some embodiments, the disposable or reusable housing defining or including the reservoir can contain a pharmaceutical formulation of the present teachings. In various embodiments, the subcutaneous injection needle can be a disposable component of the device. When administered for the treatment or inhibition of a particular disease state, condition or disorder, it is understood that an effective dosage can vary depending upon many factors such as the particular compound or therapeutic combination utilized, the mode of administration, and severity of the condition being treated, as well as the various physical factors related to the individual being treated. In therapeutic applications, a compound or therapeutic combination of the present teachings can be provided to a patient already suffering from a disorder, for example, subcutaneous adipose tissue, in an amount sufficient to reduce and/or prevent the symptoms of the disorder and its complications. The dosage to be used in the treatment of a specific individual typically must be subjectively determined by the attending physician. The variables involved include the specific condition and its state as well as the size, age and response pattern of the patient.

The term “about” when used in conjunction with a numerical value indicates the value is within 10% of the numerical value. In embodiments, “about” means within 5% of the numerical value. In embodiments, “about” means within 1% of the numerical value. For example, about 1.0% means 0.9% to 1.1%. It will be understood that the indicated value is included as an embodiment within the range specified by the use of “about” referring to the numerical value. In embodiments, “approximately” when applied to a numerical value has the same meaning as “about”.

The term “buffer” is used in accordance with its common meaning within the biological sciences and refers to a solution including a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer has the property that the pH of the solution changes very little when a small amount of acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. Examples of suitable buffers include phosphate buffers and those known in the literature (see, for example, Troy, D. B., ed. (2005) Remington: The Science and Practice of Pharmacy, 21st ed., Lippincott Williams & Wilkins).

For example, the pharmaceutical formulation may be split into 5, 10, 15, 20, 25 or 30 separate pharmaceutical formulations and, in some cases, up to 50 separate pharmaceutical formulations. In embodiments, each such smaller pharmaceutical formulation is itself a pharmaceutical formulation and may have a volume described herein.

Provided herein is a solution to an unmet and long-felt need in the cosmetic and aesthetic industry for an emulsifying detergent formulation for reducing fat deposits that overcomes the shortcomings and failures of previous attempts in the field. In particular, provided herein are injectable formulations for treating or contacting fat cells, regional adipose tissue, regional adiposity, or regional fat accumulation. In embodiments, the formulations described herein include an effective amount, including for example a therapeutically or cosmetically effective amount, of polidocanol, polidocanol-like compound, or a pharmaceutically acceptable or cosmetically acceptable salt or other suitable form thereof and a liquid carrier including aqueous carriers; wherein the polidocanol, polidocanol-like compound and the liquid carrier are formulated for injection into a layer of fat, including subcutaneous fat, in the individual in need thereof. In embodiment, the formulations do not include a lipase. In embodiment, the formulations do not include a colipase.

In embodiments, the polidocanol produced herein results in a mixture of unbranched, saturated C12 primary alcohol ethoxylate homologues having a range of ethoxide units (see, e.g. FIGS. 1 and 2). For example, HPLC characterization of embodiments of product polidoconal synthesized herein results in approximately 15 peaks associated with varying numbers of ethoxide units (FIG. 1). In the polidoconal product characterized in FIG. 1, for example, no single peak makes up more than 10% of the total mixture. The average ethoxylation number of the polidoconal characterized in FIG. 1 (and provided herein) is 6-7 and the average molecular weight is approximately 493 g/mol.

In embodiments, potassium hydroxide is used as the catalyst to produce polidocanol from ethylene oxide (e.g. 9 moles) and dodecanol (e.g. 1 mole).

Polidocanol products with different ranges or percentages of ethoxylate homologues may be produced using different catalysts (e.g. different metal oxide catalysts). See e.g. Van OS, N. M., Nonionic Surfactants—Organic Chemistry, Marcel Dekker Inc., New York, 1998, p. 101 at FIG. 4A-C. In embodiments, the polidocanol includes fewer than 15 major peaks (e.g. 10 or less) as shown by HPLC characterization. The polidocanol may include about 7 to about 11 ethoxylate units.

In embodiments, the product polidocanol includes alkyl ethoxylate homologue mixtures containing a high proportion of detergent/surfactant homologues per gram of mixture produced (e.g., by the methods provided herein).

In embodiments, polidocanol is formulated with a co-solvent. The co-solvent may be propylene glycol.

In embodiments, the intravascular formulation of polidocanol contains ethanol at approximately 5% to improve formulation stability (particularly at lower temperatures) and to reduce foaming. Ethanol is suitable for intravascular administration due to its rapid dilution by the blood. However, for subcutaneous administration, where the injected formulation resides longer at the administration site, ethanol is not ideal. Ethanol is irritating when administered subcutaneously and can cause burning, swelling, redness, and skin discoloration secondary to inflammation. In addition, ethanol is generally toxic to a variety of tissues and may limit the selective effect of polidocanol on subcutaneous fat tissue, resulting in more complications.

Hydrophilic-Lipophilic Balance (“HLB”)

In some embodiments, provided is a formulation including a polidocanol of Formula I or Formula II (e.g., polidocanol) that has an HLB value of from about 10 to about 15. Changing the nature of the hydrophobic hydrocarbon alkyl tail of a compound of Formulas I or II such as increasing or decreasing the length or the degree of saturation can affect the HLB. The length of the hydrophilic head (e.g., a polyether) of a compound of Formulas I or II can also affect the HLB. For example, too many polyethers can cause the compound to be too water soluble and act like ionic detergent and have unwanted effects on healthy tissue (e.g., adjacent, surrounding, non-fat tissue). On the other hand, too few polyether groups the compound will render the compound not soluble or immiscible (e.g., crystallization, aggregation) in aqueous solution causing formulation and manufacture complications (e.g., non-uniform formulation), and in turn decreased effectiveness (e.g., non-uniform adipose reduction over an area or non-uniform reduction of adipocytes over an area, patchiness of fat reduction). Thus, the disclosed n values of the compounds of Formulas I and II as described herein are desirable.

In some embodiments, provided is a formulation including a compound of Formula I or Formula II (e.g., polidocanol) that has an HLB value of from about 11-14, of about 12-13, of about 12.5-13.5, of about 11, of about 12, about 13, of about 14, or of about 15.

For example, reductions in inguinal fat pad mass of 15% were found at day 28 after a single treatment of polidocanol at doses of 0.5% and 1.25% (FIG. 3). Higher concentrations (2.0%) were shown to yield slightly less (10%) fat pad mass reductions. Thus, in embodiments, the polidoconal is administered approximately once per month and/or at concentrations less than about 2.0%. The treatment may employ about 0.1 to 0.3 ml (e.g. 0.2 ml) of a polidocanol at a concentration provided herein. In embodiments, the polidocanol is a concentration of from about 0.5% and 1.25%. The administration may be via injection. In embodiments, the injection is at a spacing of about 0.2 to 0.8 cm apart across the inguinal fat pad. Thus, in embodiments, the polidoconal is administered approximately once per month and/or at concentrations less than 2.0%. The treatment may employ 0.1 to 0.3 ml (e.g. 0.2 ml) of a polidocanol at a concentration provided herein. In embodiments, the polidocanol is a concentration of from 0.5% and 1.25%. The administration may be via injection. In embodiments, the injection is at a spacing of 0.2 to 0.8 cm apart across the inguinal fat pad. In embodiments, the injection is at a spacing of about 0.5 cm apart across the inguinal fat pad (FIGS. 4A-4C). As shown in FIG. 3, the reductions in fat pad mass in this example were at least equivalent to deoxycholate administered at the same optimized dosing frequency, volume, and injection spacing. In addition, externally visible reduction in inguinal fat pad fullness was observed resulting in enhancement of the inguinal crease consistent with a benefit of visible changes in body contour (FIG. 5A-5B).

In an aspect, provided herein is a method of treating regional adipose tissue, regional adiposity, sub-mental adiposity, or regional fat accumulation in an individual, said method including administering to the individual an effective amount of a formulation including: at least one of a compound of Formula I or Formula II such as polidocanol or a pharmaceutically acceptable or cosmetically acceptable salt or other suitable form thereof; and a liquid carrier; wherein the compound of Formula I or Formula II or a pharmaceutically acceptable or cosmetically acceptable salt or other suitable form thereof and the liquid carrier are formulated for injection into a layer of subcutaneous fat in the individual in need thereof.

In embodiments, the administration of polidocanol is provided in a manner that selectively destroys adipose cell relative to skin cells (e.g. dermal cells). In FIGS. 4, 5A, 5B, 6, 7 and 8A-8C, it is shown that a polidocanol concentration greater than about 1.25% is associated with a higher proportion of side effects such as skin necrosis, inflammation, and the formation of large subcutaneous fat droplets that are slowly cleared from the body.

FIG. 6 shows that polidocanol selectively destroys fat tissue relative to skin tissue. When compared to the current detergent/surfactant standard for injectable subcutaneous fat destruction, deoxycholate (an ionic monomeric molecular species detergent), polidocanol injection at 0.5% and 1.25% resulted in 1 of 9 (11%) animals with mild skin breakdown whereas 3 of 5 (60%) of animals injected with 1% deoxycholate developed severe skin necrosis (FIG. 6). Moreover, 2% polidocanol produced less skin necrosis (33%) than deoxycholate. Thus, in embodiments, polidocanol is safer than deoxycholate for local fat reduction.

In some embodiments, in addition to treating a subject with any of the compositions described herein, a physician or other authorized medical caregiver prescribes a liposuction procedure to a subject, or performs a liposuction procedure on the subject to further reduce regional fat deposits.

EXAMPLES Example 1: Pre-Clinical Study—Effect of Polidocanol on the Inguinal-Lateral Fat Pad (ILFP) of Hamsters

Concentration of polidocanol solutions: 0.5%, 1.25% and 2%; Deoxycholate dose concentration: 1.0%

Species: LVG Syrian Golden Hamsters, retired breeders

Body weight: 165-187 grams (on first day of treatment period); Sex: Male; Vendor: Charles River; Diet: Standard lab chow; Randomization: Animals were grouped so that the mean body weights are approximately equal among the treatment subgroups

Model: The inguinal fat pads were used as a model tissue. In the golden hamster, these subcutaneous fat pads lying bilaterally in the inguinal region were continuous with fat pads located laterally on each respective flank, and thus were referenced here as inguinal-lateral fat pads or ILFPs. The length of each fat pad offered the opportunity for two injections spaced approximately 4 cm apart within each fat pad, and similarly placed control injections in the contralateral fat pad of the same animal. The unilateral experimental treatment in this model offered the advantage of paired comparison of treated and non-treated fat pads within individual animals, and served as a model to assess lipolytic effects of test compounds.

Test Articles: Polidocanol: Solutions provided by Advantar (or other), 0.5%, 1.25%, and 2.0%, formulated with propylene glycol.

Treatment: Under isoflurane anesthesia, the right ILFP was injected with 0.2 cc of drug solution at two sites (medial and lateral portions of the ILFP), spaced 0.5 cm apart. The left ILFP was injected in medial and lateral sites with filtered vehicle control solution. A total of 36 animals were divided into three dose groups, outlined in the following table:

TABLE 1 Division of animals in treatment groups Polidocanol/ Deoxycholate dose Sacrifice Grp. (concentration) Treatment(s) Route, Dosing Regimes and harvest n 1 0.5% Days 0, 28 0.2 ml, subcutaneously Day 28 (n = 4), 9 into inguinal fat pad, 3 56 (n = 5) injection 0.5 cm apart 2  1.25% Days 0, 28 0.2 ml, subcutaneously Day 28 (n = 4), 9 into inguinal fat pad, 3 56 (n = 5) injection 0.5 cm apart 3 2.0% Days 0, 28 0.2 ml, subcutaneously Day 28 (n = 4), 9 into inguinal fat pad, 3 56 (n = 5) injection 0.5 cm apart 4 1.0% Day 0 0.2 ml, subcutaneously Day 28 5 (Deoxycholate) into inguinal fat pad, 3 injection 0.5 cm apart

Harvesting: On day 28 (injections at Day 0) and 56 (injections at Day 0 and Day 28), the animals were sacrificed and the ILFPs excised and weighed (see “INGUINAL/LATERAL FAT PAD HARVESTING PROCEDURE,” below). Medial and lateral portions of each ILFP were weighed together. After weighing, each portion was frozen separately on dry ice and stored frozen for histological analysis.

Fat weight analysis: Results were expressed primarily as the mean difference between the right and left ILFPs in grams (A R-L) and as the percent difference (A R-L %). Statistical analysis was performed.

Histological analysis: The right (polidocanol treated) medial injection sites of all six subjects, and one left (saline treated) site from each treatment group (animals #3 and #5), were analyzed histologically to determine evidence of necrosis within the adipose tissue. The selected samples were sectioned at a thickness of 20 microns taken at intervals of 0.5 mm through the tissue. The sections were mounted and stained with H&E and examined microscopically for evidence of necrosis or inflammation. Representative images of each tissue were recorded with a Carl Zeiss color camera. Although necrosis or inflammation cannot be determined definitively by visual inspection of the H&E stained sections, infiltration of the tissue by foreign (non-adipose) cells is interpreted as an inflammatory response (which can be suggestive of a necrotic event).

Histopathology of normal adipose tissue is nearly devoid of inflammatory cell infiltration and shows very thin cell membranes surrounding lipid droplets with occasional strands of connective tissue separating different lobules of fat cells. Histopathology of adipose tissue treated with polidocanol shows dose dependent changes of fat cell necrosis and apoptosis leading to large vacuolar areas separated by thicker fibrotic septa and generalized fibrotic changes. In addition, there is a lymphomononuclear inflammatory infiltrate with macrophage phagocytosis of lipid cell debris.

Injection and Harvesting Procedures

Inguinal Injection Procedure (0.2 cc volume, 0.5 cm apart)

The animals were injected percutaneously with 0.2 mL/injection of test article solution at up to four (4) sites (in the medial, central, and lateral portions of the ILFP) running superiorly to caudally, spaced 0.5 cm apart. The injections were carried out by inserting the needle into the right inguinal region, locating the tip of the needle in the middle of the fat pad between the peritoneal wall and the right leg. In hamsters, the fat could be roughly visualized as a light area beneath the skin. The tip of the needle was at a depth adequate to enter the inguinal fat (as discerned by the thickness of tissue when the needle tip is raised slightly upward while in its final position) while avoiding the leg muscle and the peritoneum. The needle tip was placed approximately 0.5 cm medial to a line drawn from the patella of the knee to the xyphoid appendix of the sternum.

Inguinal-Lateral Fat Pad Harvesting Procedure (Hamster)

With the animal lying ventral side up, skin was cut along abdominal midline from the umbilicus to a point caudal to the penis near the bottom of the scrotum. The skin was cut from the penile area in a posterior and lateral direction toward the posterior of the hindlimb. From the superior end of the midline incision (near umbilicus), skin was cut bilaterally along the flank in a dorsal direction to the spinal region, forming triangular skin flaps over the abdomen. An elipse was harvested of skin overlying the region of the ILFP, and placed in formalin for storage and. Carefully reflected each skin flap away from the fat (remove fat attached to skin), using blunt dissection combined with incision of fascia as needed. The peritoneum and scrotal sac were exposed, as well as the inguinal area to beyond the knee and along the flanks. The inguinal fat pad was tan in color and lied primarily in the inguinal crease between the abdomen and hind leg diagonally medially from the tail to laterally toward the head. The fat pad was contiguous with a thin sheet of subcutaneous fat that wraps dorsally over the lateral side of the animal and medially across to the contralateral fat pad. The fat along the abdominal midline was cut, separating the right and left fat pads. The inguinal fat was dissected away from the peritoneum in the crease. Using blunt dissection underneath the pad, the pad was separated from underlying attached muscle from the ventral midline section to the inferio medial and dorsal lateral end of the pad avoiding removal of the thin areas that begin to fan out dorsal laterally over the side of the animal. The superior border was cut parallel along a line from the knee to the xiphoid process. Care was taken to harvest both the right and left fat pad according to the same anatomical boundaries so to avoid harvesting excess fat on one side versus the other. The treated side was more fibrotic and reduced in size over the vehicle side.

Example 2: Phase III Clinical Study

A multicenter, phase III, randomized, double-blind, placebo-controlled, parallel-group study can evaluate the efficacy and safety of polidocanol administered at fixed doses of 0.5% W/V and 1.0% W/V. The study is divided into a screening period (week −8 to baseline; visit 1), followed by a 12-week treatment period (visits 2-5) and a 12-week efficacy and safety follow-up period (visits 6 and 7).

Inclusion and Exclusion Criteria

Men and women aged 18-65 years are eligible to participate if they present with moderate or severe sub-mental fat (“SMF”) [grade 2 or 3 on the 5-point Clinician-Reported Sub-mental Fat Rating Scale (CR-SMFRS)] and express dissatisfaction with the appearance of their sub-mental area [Subject Self-Rating Scale (SSRS) score 0-3] at visit 2. Patients will agree to undergo clinical evaluations and laboratory tests and to maintain stable body weight, diet and exercise practices during the study. Women of reproductive age are required not to be pregnant or lactating and to practice birth control during the study. The principal exclusion criteria will be: previous intervention to treat SMF; anatomical features or previous trauma liable to interfere with SMF evaluation or result in an aesthetically unacceptable outcome after treatment; evidence of any cause of sub-mental enlargement other than SMF; and any medical condition likely to affect safety or efficacy assessments or the patient's ability to undergo study procedures or provide informed consent. Patients with a body mass index (BMI)>30 kg m⁻², those undergoing or considering a weight-reduction program, and patients with a history of sensitivity to any components of the study material or topical or local anaesthetics will also be excluded.

Randomization

Patients will be randomized (1:1:1) at visit 2, after completion of baseline evaluations, through allocation of a unique randomization number using a computerized web/voice-response system. Polidocanol and placebo treatment kits will have an identical appearance and carried a blinded label with a random kit number; these will be assigned to patients using the computerized system.

Interventions

All randomized patients will have at least one treatment session, with a maximum of four sessions, separated by 28±5 day intervals (visits 2-5). Patients will receive up to 10 mL of the study drug per treatment session, and the number of sessions will be dependent on the amount of remaining SMF and each patient's satisfaction with the appearance of their face and chin. Injections will be administered subcutaneously directly into the pre-platysma SMF at a volume of 0.2 mL per injection and spaced approximately 1 cm apart using a grid to provide even coverage. Topical anesthesia will be provided, if needed. Premature treatment discontinuation could occur owing to adverse events (AEs), early therapeutic success or at the patient's request. The treatment area will be evaluated 7±3 days after each treatment and concomitant medication use was reported. Patients will attend two follow-up visits (visits 6 and 7) 4 weeks (±5 days) and 12 weeks (±7 days) after the final treatment session.

Efficacy Outcome Measures

Efficacy endpoints will be evaluated at visit 7 (12 weeks after final treatment). There will be two co-primary efficacy endpoints: the proportion of treatment responders, i.e. with a reduction in SMF of ≥1 point on the 5-point CR-SMFRS relative to baseline, and the proportion of patients satisfied with their appearance in association with their face and chin (i.e. with a score of ≥4 on the 7-point SSRS rating scale). To confirm the primary endpoint results, sensitivity analyses will be conducted on the secondary parameters of change from baseline in CR-SMFRS and SSRS scores, and changes in caliper measurements of SMF thickness, by treatment session. The effect of treatment on skin laxity (Skin Laxity Rating Scale, SLRS) will also be evaluated, and patient-reported outcomes were assessed using the Patient-Reported Submental Fat Rating Scale (PR-SMFRS) and Patient-Reported Submental Fat Impact Scale (PR-SMFIS). Additional patient-reported instruments will also be used.

Safety Outcome Measures

AEs will be evaluated at each visit and approximately 7 days after each treatment session, and were characterized descriptively by the day on which they started and stopped, and by severity and intensity. Treatment-emergent AEs will be defined as those with onset or exacerbation after the first treatment dose. Changes from baseline in clinical laboratory parameters and other tests, and variations in vital signs, body temperature and body weight, will also be measured.

Statistical Methodology

Using 80% of the effect size observed in two previous placebo-controlled and a 10% dropout rate per treatment group with a Pearson chi-square test for two proportions (two-sided test with α=0.025), a conservatively rounded sample size of 120 patients per treatment group will be used to guarantee a power of 90%.

The efficacy analyses is based on the intention-to-treat population (all randomized patients who had at least one efficacy assessment at baseline), with missing values at visit 7 imputed using last observation carried forward. The null hypothesis for the treatment comparisons is that there was no difference between each dose of polidocanol and placebo for the two co-primary efficacy endpoints. Comparisons of the two polidocanol dose groups with placebo is made via odds ratios from binary logistic regression. An adjustment for multiplicity was performed. Because there were two co-primary endpoints, the null hypotheses for both variables had to be rejected at the same significance level (α=0.05). This is accounted for by using the larger of the two P-values in the Bonferroni-Holm procedure.

For the secondary endpoints, changes from baseline in CR-SMFRS and caliper scores are analyzed using a mixed-models repeated-measures analysis. Changes from baseline in SSRS scores are analyzed by an analysis of variance (ANOVA). PR-SMFRS improvements of ≥1 point are analyzed by binary logistic regression. Changes from baseline in SLRS scores are recorded in frequency tables and Pearson's chi-square test was applied to compare each polidocanol group with placebo. Descriptive statistics were calculated for PR-SMFIS scores, with the change from baseline analyzed by a post hoc Fisher's least-square difference test for continuous variables, only if ANOVA show an overall treatment effect. Statistical summaries for AEs are based on treatment-emergent AEs in the safety population (all patients who received at least one treatment with study drug). The numbers of AEs and patients presenting with each AE are categorized according to association with treatment, study withdrawal, death, severity, intensity, system organ class and preferred term.
